[Shotimes] A whole bunch of things got fixed

[Rob Pittman]

While doing a clutch job in my 90, I found the rear motor mount was in two 
interlocked pieces.  Also, the front was nearly as bad.  I suspected the 
front was bad since I had a polished spot on the intake, but I'd never 
heard of a rear motor mount letting go like this one did.  I had been 
having trouble with mild overheating (running in the "O" to "R" range), and 
occasional CPS problems which I thought were due to the expansion tank 
venting and blowing coolant back on the CPS.  I had previously replaced 
every sensor that was coolant related, flushed the system, burped it when 
filling, etc. The water pump was replaced three to four months ago and not 
leaking.  The CPS was new, so I was getting pissed I'd put in a bad sensor 
new from FoMoCo.  The car was also stumbling when starting from a dead 
stop, which I was attributing to the old clutch getting grabby.  Also, the 
expansion tank had broken loose from the bracket, which I repaired with 
some J-B Weld (a new one was $86 from the stealership).

The old PP had five fingers broken, and the old TOB was missing half a 
dozen balls out of the race.

After replacing the MMs, the car is running down in the "A" to "L" range 
even in traffic, no CPS problems have recurred (knocking on wood 
here),  and the hesitation has stopped.

I'm wondering if the engine was getting pitched at a weird angle, pinching 
the lower radiator hose, and causing some type of overpressure situation in 
the cooling system, making the car run hotter than normal and blowing 
coolant out of the expansion tank.  With the motor at a weird angle, the 
CPS may have been exposed to the blowback of coolant from the expansion 
tank.  The CPS problems always seemed to happen at highway speeds.  Anybody 
encountered anything similar?
